osu!catch: Add option to hide fruit stacks in catcher during No-mod gameplay

[syzyxy]

Playing Hidden (and the catch editor) does this and it reduces lag significantly since clearing of fruits in the platter can result to lag especially when the combo is long. Much better if this can be done by default; this will definitely help a lot of ctb players transition to lazer as their main version to play.

Let's just remove all the gameplay of the game. I love it.

I just thought it'd be quite a big performance boost when playing ctb maps since this is mostly the concern among top players using the stable vesion especially on lengthy combos. Having this option may encourage more ctb players to move to lazer. Besides, ctb isn't strictly a "rhythm game" to the same extent as the other modes, so the "New combo" feature doesn't really provide much help in gameplay unlike in std. It is already present when playing with HD and using the catch editor; I don't see any value lost when this is done unless I guess sentimentally-speaking.
